I was cycling along the tow path of a wide river in France when I came to a quiet stretch where there was a bench so I decided to stop and have a pee and a cigarette. After finishing my pee I sat down and lit up. After a moment or two I noticed a movement on the opposite bank and a naked man emerged from behind a tree. His average sized cock was sticking straight out in front of him and he started to stroke it.
I am not gay but do like to look at stiff tools, I'm also a bit of an exhibitionist, so as there was no one around I dropped my shorts and started to rub my now hardening cock. The man across the river watched me and continued to pleasure himself. After nearly sixty years of wanking this was an entirely new experience for me and it wasn't too long before I came. I mopped up with my hankie and waved it at his to show him I was finished. A moment later he was gone and just as I was pulling up my shorts a jogger came round the corner. He must have seen me!
